Guilt, whether it be religious or liberal, has never made anybody better people. It has merely changed their outward behavior (through fear). REAL bigots often patronize those who would be offended by their actual thoughts. YOU GET PATRICK BATEMAN! Understanding (experience with others) and humor (OPEN communication, not eggshells) change people. EDIT: So perhaps instead of telling people they are wrong for the fun they are having, help them to figure it out for themselves. Harassment isn't going to work the way you think it should.
